3 Claims. (Cl. 114-208) The present invention relates to new and useful improvements in anchors for boats and more particularly to an anti-fouling anchor to reduce the strain and effort required to raise the anchor from an embedded position or to release the anchor from a submerged object.

An important object of the invention is to construct the anchor with a shank adapted for lockable engagement with a rockable transverse shaft to which the anchor flukes are secured to retain the flukes at an effective anchoring angle to the shank and to the direction of pulling force of a boat tied to the shank and to unlock the shank from the shaft by a forward movement of the boat whereby the shank will be free to swing relative to the flukes to easily retract the latter from their embedded position.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being bad to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout,

' and in which:

Figure 1 is a perspective view;

Figure 2 is a view on a reduced scale showing the anchor in anchoring and releasing position;

Figure 3 is a vertical sectional view taken on a line 33 of Figure 1;

Figure 4 is a transverse sectional view taken on a line 4-4 of Figure 3;

Figure 5 is an enlarged fragmentary sectional view taken on a line 55 of Figure 3;

Figure 6 is a fragmentary vertical sectional view taken on a line 66 of Figure 3 and showing the anchor in anchoring position; and

Figure 7 is a similar view showing the anchor in releasing position.

Referring now to thedrawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 5 designates a hollow cylindrical housing having a closed lower end 6 and in which the lower end of an anchor shank 7 is rotatable and slidable.

A pair of apertured spaced apart brackets 8 and 9 are welded to the opposite sides of the housing 5 to project below the latter and a shaft 10 is rotatably mounted in aligned openings 11 and 12 in the brackets to support the shaft in a transverse position at the lower end of the housing. A pair of sheet metal flukes 13 and 14 are welded at one edge portion to the shaft at opposite sides of the housing. A sleeve 15 is rotatably mounted on the shaft 10 between the brackets 8 and 9 and is formed with a circumferential slot 16 to receive a stop pin 17 which is threaded in the shaft to limit rotation of the sleeve in opposite directions. The sleeve is also formed with a socket or recess 18 to receive the lower end of the shank 7 to lock the sleeve 15 and shaft 10 to the shank to limit swinging of the flukes relative to the hired States O Fr" ce 7 2 shank to the range of movement provided by the slot 16 and stop pin 17.

The upper end of shank 7 projects outwardly at the upper end of the housing 5 and is provided with an eye 19 for attaching an anchor rope 20 thereto. A pair of lugs 21 and 22 projects inwardly in opposed relation to each other at the upper end of the housing and between which the shank is slidable and a pin 23 projects transversely of the shank for movement into and out of locking engagement with the underside of the pair of lugs to lock the lower end of the shank in the socket or recess 18 of sleeve 15.

A coil spring 24 surrounds the lower portion of the shank 7 and is held under spring tension thereon between the lower end 6 of the housing and a washer 25 fixed to the shank to urge the shank upwardly for disengaging the sleeve 15. A stop and guide washer 26 is welded to a pair of transverse pins 27 and 28 in housing 5 in the path of upward movement of the washer 25 to limit raising movement of the shank relative to housing 5 and the shank is slidable in washer 26.

With the shank 7 forced downwardly in housing 5 to enter socket or recess 18 and the shank turned to lock the pin 23 with lugs 21 and 22 the shank and shaft 10 will be locked to each other for limited rotary movement of the shaft relative to the shank. In this position the flukes of the anchor will project at an acute angle at one side of housing 5 for embedding in the bottom of a body of water at a desired angle for effectively anchoring a boat 30 and with the strain subjected at an angle to the flukes, as shown by full lines in Figure 2. In order to free the anchor the boat is driven or moved in a direction to swing the shank 7 and housing 5 to a new position, as shown by dotted lines in Figure 2. Shank 7 is pulled in this way to release pin 23 from engagement with lugs 22 and 21. The spring 24 raises shank 7 from recess 18 whereby the flukes are movable to being lifted from the water, and the anchor may then be more easily raised.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. An anchor comprising a hollow elongated housing, a shank slidably and rotatably mounted in the housing and projecting outwardly at each end thereof, a transverse shaft rotatably supported at one end of the housing and having a pair of anchor flukes fixed to the end portions of the shaft, sleeve means on said shaft detachably securing the shank to the shaft to restrain relative rotation of the latter, said shank being released from the shaft by a sliding movement of the shank in the housing, and pin means on said shank cooperating with said housing lockably connecting the shank to the housing, said last named means including a locking pin actuated into a locking or unlocking position by a turning movement of the shank relative to the housing.

2. An anchor comprising a hollow elongated housing, a shank slidably and rotatably mounted in the housing and projecting outwardly at each end thereof, a transverse shaft rotatably supported at one end of the housing and having a pair of anchor flukes fixed to the end portions of the shaft, sleeve means on said shaft detachably securing the shank to the shaft to restrain relative rotation of the latter, said shank being released from the shaft by a sliding moving of the shank in the housing, and pin means on said shaft cooperating with said housing lockably connecting the -shank to 'thehousing, said last named means including lngs on the housing anda locking member on the shank movable into and out of engagement with the lugs by a turning movement of the shank relative tothehousing;

3. The construction of claim 1 and includingtspring ing the shank ina releasing position.
